The Adrenaline high-volume high pressure oil pump is the perfect solution for any injector setup. 
This is a heavy-duty, bolt-on replacement HPOP that benefits all setups – even stock trucks with stock programming will see and feel a difference.
You will experience more pulling power, better fuel economy, horsepower increase (increase changes based on injector size), and quicker startups.
The Adrenaline has been on the market for nearly 15 years and is tried and true by the 7.3L community.  Our units are upgraded with custom internals and design changes to get the most out of a single housing pump while improving reliability over the stock unit.
Every Adrenaline leaves tested to the same flow rate specifications prior to shipment – NO UNIT LEAVES UNTESTED.
All year Adrenaline HPOPs – including the 1994-1995 – are built to be able to use the 1996-2003 Injector Pressure Regulator.
What advantage does the BILLET model have?
DIESELSITE does everything we can to quality control the integrity of cores and core housings received, however, there are some designs on the original cast housing prone to failure that are unavoidable.
Our billet housing addresses all of those concerns – including thread strengths & common leak locations – to offer a more robust and modern heart for your motor.

*We offer a 3 year unlimited warranty covering the unit for anything short of abuse, tampering, and obvious physical damaged caused by user.
There are two options to purchase:
a) you may pay a core charge and have a unit shipping prior to your core return
b) you may send your core up ahead and avoid the core charge – we will email you instructions on where to send the core up ahead if you choose this option
*If your core has irreparable damage done to the housing, there will be only a partial credit return.
*Please call the office if you have concerns on your core unit in regards to unusual external damage.
You have 45 DAYS to return your pump core for a full core charge refund.  You can send any year 7.3L for a core return; we will accept your core return after the return period but fees may be involved if there has been too long of a delay.  Please call if you know you will need more time on your return.
If you send additional cores with the original, we will credit an extra $150 per unit – any 1994-2003 7.3L model.


You do not need to purchase an Adrenaline to receive this credit, please call the office if you have cores to sell!
The Adrenaline comes with a 3 year unlimited mile warranty.
